Meet The Smart Contact Lenses Powered By Tears

Researchers in Singapore have revolutionized the humble contact lens with self-charging smart capabilities.

Contact lenses have been used to successfully correct vision for decades, but recently, they’re beginning to evolve into something much more interesting.

Researchers from the Nanyang Technological University (NTU) in Singapore have developed a tiny micrometer-thin battery that can power futuristic smart contact lenses that rely on the wearer’s tears for power.

Although smart contacts are nothing new, most attempts so far have relied on thin batteries with tiny induction coils and wires. Obviously, these metal parts aren’t ideal for a device that sits directly on the wearer’s eye, so an NTU School of Electrical and Electronic Engineering (EEE) research team led by Lee Seok Woo has been working on something better.

According to a press release, the NTU team’s battery uses biocompatible materials coated with a glucose-based layer. The coating reacts with the sodium and chloride ions present in the battery to generate electricity. Since both sodium and chloride ions are also found in tears, the smart lens battery can also be recharged while in use with no additional effort from the wearer.

Speaking about the research, Lee Seok Woo said, “This research began with a simple question: Could contact lens batteries be recharged with our tears? Previous techniques for lens batteries were imperfect, as one side of the battery electrode was charged, and the other was not. Our approach can charge both electrodes of a battery through a unique combination of enzymatic reaction and self-reduction reaction”.

According to the NTU team, the lenses should be good for a full day of use, and can also be placed in a special solution that keeps the battery charged. “By combining the battery and biofuel cell into a single component, the battery can charge itself without the need for additional space for wired or wireless components. Furthermore, the electrodes placed at the outer side of the smart contact lenses ensure that the eye’s vision cannot be obstructed”.

The NTU scientists are already working on boosting the amount of electricity the lens battery can deliver. Their research has been published in the journal Nano Energy, and they’re also in the process of partnering with contact lens producers to bring the technology to the market.

Adobe Teases New AI Editing Tools And Updates In Premiere Pro

The video editing app will be enhanced with a generative extend tool, text-to-video, improved timeline waveforms, and more.



adobe teases new ai editing tools and updates in premiere pro

After launching the generative AI model Firefly last year, Adobe is now showcasing how the technology will be used in upcoming versions of the editing app Premiere Pro. In an early sneak peek, the company demonstrated several new features, including Object Addition and Removal, Generative Extend, and Text to Video.

The first new feature, Generative Extend, targets a common video editing problem by using AI to “Seamlessly add frames to make clips longer, so it’s easier to perfectly time edits and add smooth transitions”.

Meanwhile, Premiere Pro’s Object Addition & Removal tool will leverage Firefly’s generative AI to “Simply select and track objects, then replace them. Remove unwanted items, change an actor’s wardrobe or quickly add set dressings such as a painting or photorealistic flowers on a desk,” Adobe states.

Adobe also showcased another new feature that can automatically generate new film clips using a text prompt. To use the content creation tool, editors can “Simply type text into a prompt or upload reference images. These clips can be used to ideate and create storyboards, or to create B-roll for augmenting live action footage,” Adobe explained. The company seems to be commercializing this particular feature extremely quickly, considering generative AI video only appeared a few months ago.

The new additions to Premiere Pro will be added later this year, but Adobe is also introducing smaller improvements to the editing app in May. The changes include interactive fade handles to enable easier transitions, an Essential Sound badge that uses AI to “automatically tag audio clips as dialogue, music, sound effects or ambience, and add a new icon so editors get one-click, instant access to the right controls for the job”, along with effect badges and a new look for waveforms in the timeline.
